FIELD OF INVENTION

The present invention generally relates to systems and methods fortreating crude feed, and to compositions that are produced, for example,using such systems and methods. More particularly, embodiments describedherein relate to systems and methods for conversion of a crude feed thathas a residue content of at least 0.2 grams of residue per gram of crudefeed to a crude product that is (a) a liquid mixture at 25° C. and 0.101MPa, and (b) has one or more properties that are improved in comparisonto the same properties of the crude feed.

DESCRIPTION OF RELATED ART

Crudes that have one or more unsuitable properties that do not allow thecrudes to be economically transported, or processed using conventionalfacilities, are commonly referred to as “disadvantaged crudes”.

Disadvantaged crudes often contain relatively high levels of residue.Such crudes tend to be difficult and expensive to transport and/orprocess using conventional facilities. High residue crudes may betreated at high temperatures to convert the crude to coke.Alternatively, high residue crudes are typically treated with water athigh temperatures to produce less viscous crudes and/or crude mixtures.During processing, water removal from the less viscous crudes and/orcrude mixtures may be difficult using conventional means.

Disadvantaged crudes may include hydrogen deficient hydrocarbons. Whenprocessing of hydrogen deficient hydrocarbons, consistent quantities ofhydrogen generally need to be added, particularly if unsaturatedfragments resulting from cracking processes are produced. Hydrogenationduring processing, which typically involves the use of an activehydrogenation catalyst, may be needed to inhibit unsaturated fragmentsfrom forming coke. Hydrogen is costly to produce and/or costly totransport to treatment facilities.

Coke may form and/or deposit on catalyst surfaces at a rapid rate duringprocessing of disadvantaged crudes. It may be costly to regenerate thecatalytic activity of a catalyst contaminated by coke. High temperaturesused during regeneration may also diminish the activity of the catalystand/or cause the catalyst to deteriorate.

Disadvantaged crudes may include acidic components that contribute tothe total acid number (“TAN”) of the crude feed. Disadvantaged crudeswith a relatively high TAN may contribute to corrosion of metalcomponents during transporting and/or processing of the disadvantagedcrudes. Removal of acidic components from disadvantaged crudes mayinvolve chemically neutralizing acidic components with various bases.Alternately, corrosion-resistant metals may be used in transportationequipment and/or processing equipment. The use of corrosion-resistantmetal often involves significant expense, and thus, the use ofcorrosion-resistant metal in existing equipment may not be desirable.Another method to inhibit corrosion may involve addition of corrosioninhibitors to disadvantaged crudes before transporting and/or processingof the disadvantaged crudes. The use of corrosion inhibitors maynegatively affect equipment used to process the crudes and/or thequality of products produced from the crudes.

Disadvantaged crudes may contain relatively high amounts of metalcontaminants, for example, nickel, vanadium, and/or iron. Duringprocessing of such crudes, metal contaminants, and/or compounds of metalcontaminants, may deposit on a surface of the catalyst or the voidvolume of the catalyst. Such deposits may cause a decline in theactivity of the catalyst.

Disadvantaged crudes often include organically bound heteroatoms (forexample, sulfur, oxygen, and nitrogen). Organically bound heteroatomsmay, in some situations, have an adverse effect on catalysts. Alkalimetal salts and/or alkaline-earth metal salts have been used inprocesses for desulfurization of residue. These processes tend to resultin poor desulfurization efficiency, production of oil insoluble sludge,poor demetallization efficiency, formation of substantially inseparablesalt-oil mixtures, utilization of large quantities of hydrogen gas,and/or relatively high hydrogen pressures.

Some processes for improving the quality of crude include adding adiluent to disadvantaged crudes to lower the weight percent ofcomponents contributing to the disadvantaged properties. Adding diluent,however, generally increases costs of treating disadvantaged crudes dueto the costs of diluent and/or increased costs to handle thedisadvantaged crudes. Addition of diluent to a disadvantaged crude may,in some situations, decrease stability of such crude.

The process, systems, and catalysts described inthese patents, however, have limited applicability because of many ofthe technical problems set forth above.

In sum, disadvantaged crudes generally have undesirable properties (forexample, relatively high residue, a tendency to corrode equipment,and/or a tendency to consume relatively large amounts of hydrogen duringtreatment). Other undesirable properties include relatively high amountsof undesirable components (for example, relatively high TAN, organicallybound heteroatoms, and/or metal contaminants). Such properties tend tocause problems in conventional transportation and/or treatmentfacilities, including increased corrosion, decreased catalyst life,process plugging, and/or increased usage of hydrogen during treatment.Thus, there is a significant economic and technical need for improvedsystems, methods, and/or catalysts for conversion of disadvantagedcrudes into crude products with properties that are more desirable.

Contacting typically takes place in a pressure range betweenabout 0.1-20 MPa, about 1-16 MPa, about 2-10 MPa, or about 4-8 MPa. Insome embodiments in which steam is added, a ratio of steam to crude feedis in a range from about 0.01-3 kilograms, about 0.03-2.5 kilograms, orabout 0.1-1 kilogram of steam, per kilogram of crude feed. A flow rateof crude feed may be sufficient to maintain the volume of crude feed inthe contacting zone of at least 10%, at least 50%, or at least 90% ofthe total volume of the contacting zone. Typically, the volume of crudefeed in the contacting zone is about 40%, about 60%, or about 80% of thetotal volume of the contacting zone.

The TMS catalyst that includes alkali metal(s), alkaline-earth metal(s),zinc, compounds of zinc, or mixtures thereof may be prepared by mixing asufficient amount of de-ionized water, a desired amount of a transitionmetal oxide, and desired amount of Columns 1-2 metal carbonate(s),Columns 1-2 metal oxalate(s), Columns 1-2 metal acetate(s), zinccarbonate, zinc acetate, zinc oxalate, or mixtures thereof to form a wetpaste. The wet paste may be dried at a temperature from about 100-300°C. or 150-250° C. to form a transition metal oxide/salt mixture.

The transitionmetal oxide/metal salt mixture may be reacted with hydrogen to form areduced intermediate solid. The addition of hydrogen may be performed ata flow rate sufficient to provide an excess amount of hydrogen to thetransition metal oxide/metal salt mixture. Hydrogen may be added overabout 10-50 hours or about 20-40 hours to the transition metaloxide/metal salt mixture to produce a reduced intermediate solid thatincludes elemental transition metal. Hydrogen addition may be performedat a temperature of about 35-500° C., about 50-400° C., or about100-300° C., and a total pressure of about 10-15 MPa, about 11-14 MPa,or about 12-13 MPa.

The diluent may include any suitable diluent thatprovides a means to dissipate the heat of sulfurization. The diluent mayinclude solvents with a boiling range distributions of at least 100° C.,at least 150° C., least 200° C., or at least 300° C.

After heating to theelevated sulfurizing reaction temperature, the diluent/catalyst mixturemay be cooled to a temperature in a range from about 0-100° C., about30-90° C., or about 50-80° C. to facilitate recovery of the catalystfrom the mixture. The sulfurized catalyst may be isolated in anoxygen-free atmosphere from the diluent using standard techniques andwashed with at least a portion of a low boiling solvent (for example,pentane, heptane, or hexane) to produce the TMS catalyst.

An atomic ratio of an alkali metal having an atomic numberof at least 11 to an alkali metal having an atomic number greater than11, in some embodiments, is in a range from about 0.1 to about 10, about0.2 to about 6, or about 0.3 to about 4 when the inorganic salt catalysthas two or more alkali metals. For example, the inorganic salt catalystmay include salts of sodium, potassium, and rubidium with the ratio ofsodium to potassium being in a range from about 0.1-6; the ratio ofsodium to rubidium being in a range from about 0.1-6; and the ratio ofpotassium to rubidium being in a range from about 0.1-6.

Metals from Columns 8-10 include, but are not limitedto, iron, ruthenium, cobalt, or nickel. Metals from Column 6 include,but are not limited to, chromium, molybdenum, or tungsten. In someembodiments, the inorganic salt catalyst includes about 0.1-0.5 grams,or about 0.2-0.4 grams of Raney nickel per gram of inorganic saltcatalyst.

In certain embodiments, the inorganic salt catalyst also includes metaloxides from Columns 1-2 and/or Column 13 of the Periodic Table. Metalsfrom Column 13 include, but are not limited to, boron or aluminum.Non-limiting examples of metal oxides include lithium oxide (Li₂O),potassium oxide (K₂O), calcium oxide (CaO), or aluminum oxide (Al₂O₃).

The inorganic salt catalyst is, in certain embodiments, free of orsubstantially free of Lewis acids (for example, BCl₃, AlCl₃, and SO₃),Brønsted-Lowry acids (for example, H₃O⁺, H₂SO₄, HCl, and HNO₃),glass-forming compositions (for example, borates and silicates), andhalides. The inorganic salt may contain, per gram of inorganic saltcatalyst: from about 0 grams to about 0.1 grams, about 0.000001-0.01grams, or about 0.00001-0.005 grams of: a) halides; b) compositions thatform glasses at temperatures of at least 350° C., or at most 1000° C.;c) Lewis acids; d) Brønsted-Lowry acids; or e) mixtures thereof.

The inorganic salt catalyst may be prepared using standard techniques.For example, a desired amount of each component of the catalyst may becombined using standard mixing techniques (for example, milling and/orpulverizing). In other embodiments, inorganic compositions are dissolvedin a solvent (for example, water or a suitable organic solvent) to forman inorganic composition/solvent mixture. The solvent may be removedusing standard separation techniques to produce the inorganic saltcatalyst.

In some embodiments, inorganic salts of the inorganic salt catalyst maybe incorporated into a support to form a supported inorganic saltcatalyst. Examples of supports include, but are not limited to,zirconium oxide, calcium oxide, magnesium oxide, titanium oxide,hydrotalcite, alumina, germania, iron oxide, nickel oxide, zinc oxide,cadmium oxide, antimony oxide, and mixtures thereof. In someembodiments, an inorganic salt, a Columns 6-10 metal and/or a compoundof a Columns 6-10 metal may be impregnated in the support.Alternatively, inorganic salts may be melted or softened with heat andforced in and/or onto a metal support or metal oxide support to form asupported inorganic salt catalyst.

A structure of the inorganic salt catalyst typically becomesnonhomogenous, permeable, and/or mobile at a determined temperature orin a temperature range when loss of order occurs in the catalyststructure. The inorganic salt catalyst may become disordered without asubstantial change in composition (for example, without decomposition ofthe salt). Not to be bound by theory, it is believed that the inorganicsalt catalyst becomes disordered (mobile) when distances between ions inthe lattice of the inorganic salt catalyst increase. As the ionicdistances increase, a crude feed and/or a hydrogen source may permeatethrough the inorganic salt catalyst instead of across the surface of theinorganic salt catalyst. Permeation of the crude feed and/or hydrogensource through the inorganic salt often results in an increase in thecontacting area between the inorganic salt catalyst and the crude feedand/or the hydrogen source. An increase in contacting area and/orreactivity area of the inorganic salt catalyst may often increase theyield of crude product, limit production of residue and/or coke, and/orfacilitate a change in properties in the crude product relative to thesame properties of the crude feed. Disorder of the inorganic saltcatalyst (for example, nonhomogeneity, permeability, and/or mobility)may be determined using DSC methods, ionic conductivity measurementmethods, TAP methods, visual inspection, x-ray diffraction methods, orcombinations thereof.

The use of TAP to determine characteristics of catalysts is described inU.S. Pat. Nos. 4,626,412 to Ebner et al.; 5,039,489 to Gleaves et al.;and 5,264,183 to Ebner et al., all of which are incorporated herein byreference. A TAP system may be obtained from Mithra Technologies (Foley,Mo., U.S.A.). The TAP analysis may be performed in a temperature rangefrom about 25-850° C., about 50-500° C., or about 60-400° C., at aheating rate in a range from about 10-50° C., or about 20-40° C., and ata vacuum in a range from about 1×10⁻¹³ to about 1×10⁻⁸ torr. Thetemperature may remain constant and/or increase as a function of time.As the temperature of the inorganic salt catalyst increases, gasemission from the inorganic salt catalyst is measured. Examples of gasesthat evolve from the inorganic salt catalyst include carbon monoxide,carbon dioxide, hydrogen, water, or mixtures thereof. The temperature atwhich an inflection (sharp increase) in gas evolution from the inorganicsalt catalyst is detected is considered to be the temperature at whichthe inorganic salt catalyst becomes disordered.

In some embodiments, an inflection of emitted gas from the inorganicsalt catalyst may be detected over a range of temperatures as determinedusing TAP. The temperature or the temperature range is referred to asthe “TAP temperature”. The initial temperature of the temperature rangedetermined using TAP is referred to as the “minimum TAP temperature”.

The emitted gas inflection exhibited by inorganic salt catalystssuitable for contact with a crude feed is in a TAP temperature rangefrom about 100-600° C., about 200-500° C., or about 300-400° C.Typically, the TAP temperature is in a range from about 300-500° C. Insome embodiments, different compositions of suitable inorganic saltcatalysts also exhibit gas inflections, but at different TAPtemperatures.

The magnitude of the ionization inflection associated with the emittedgas may be an indication of the order of the particles in a crystalstructure. In a highly ordered crystal structure, the ion particles aregenerally tightly associated, and release of ions, molecules, gases, orcombinations thereof, from the structure requires more energy (that ismore heat). In a disordered crystal structure, ions are not associatedto each other as strongly as ions in a highly ordered crystal structure.Due to the lower ion association, less energy is generally required torelease ions, molecules, and/or gases from a disordered crystalstructure, and thus, a quantity of ions and/or gas released from adisordered crystal structure is typically greater than a quantity ofions and/or gas released from a highly ordered crystal structure at aselected temperature.

In some embodiments, a heat of dissociation of the inorganic saltcatalyst may be observed in a range from about 50° C. to about 500° C.at a heating rate or cooling rate of about 10° C., as determined using adifferential scanning calorimeter. In a DSC method, a sample may beheated to a first temperature, cooled to room temperature, and thenheated a second time. Transitions observed during the first heatinggenerally are representative of entrained water and/or solvent and maynot be representative of the heat of dissociations. For example, easilyobserved heat of drying of a moist or hydrated sample may generallyoccur below 250° C., typically between 100-150° C. The transitionsobserved during the cooling cycle and the second heating correspond tothe heat of dissociation of the sample.

“Heat transition” refers to the process that occurs when orderedmolecules and/or atoms in a structure become disordered when thetemperature increases during the DSC analysis. “Cool transition” refersto the process that occurs when molecules and/or atoms in a structurebecome more homogeneous when the temperature decreases during the DSCanalysis. In some embodiments, the heat/cool transition of the inorganicsalt catalyst occurs over a range of temperatures that are detectedusing DSC. The temperature or temperature range at which the heattransition of the inorganic salt catalyst occurs during a second heatingcycle is referred to as “DSC temperature”. The lowest DSC temperature ofthe temperature range during a second heating cycle is referred to asthe “minimum DSC temperature”. The inorganic salt catalyst may exhibit aheat transition in a range between about 200-500° C., about 250-450° C.,or about 300-400° C.

In an inorganic salt that contains inorganic salt particles that are arelatively homogeneous mixture, a shape of the peak associated with theheat absorbed during a second heating cycle may be relatively narrow. Inan inorganic salt catalyst that contains inorganic salt particles in arelatively non-homogeneous mixture, the shape of the peak associatedwith heat absorbed during a second heating cycle may be relativelybroad. An absence of peaks in a DSC spectrum indicates that the saltdoes not absorb or release heat in the scanned temperature range. Lackof a heat transition generally indicates that the structure of thesample does not change upon heating.

As homogeneity of the particles of an inorganic salt mixture increases,the ability of the mixture to remain a solid and/or a semiliquid duringheating decreases. Homogeneity of an inorganic mixture may be related tothe ionic radius of the cations in the mixtures. For cations withsmaller ionic radii, the ability of a cation to share electron densitywith a corresponding anion increases and the acidity of thecorresponding anion increases. For a series of ions of similar charges,a smaller ionic radius results in higher interionic attractive forcesbetween the cation and the anion if the anion is a hard base. The higherinterionic attractive forces tend to result in higher heat transitiontemperatures for the salt and/or more homogeneous mixture of particlesin the salt (sharper peak and increased area under the DSC curve).Mixtures that include cations with small ionic radii tend to be moreacidic than cations of larger ionic radii, and thus acidity of theinorganic salt mixture increases with decreasing cationic radii. Forexample, contact of a crude feed with a hydrogen source in the presenceof an inorganic mixture that includes lithium cations tends to produceincreased quantities of gas and/or coke relative to contact of the crudefeed with a hydrogen source in the presence of an inorganic saltcatalyst that includes cations with a larger ionic radii than lithium.The ability to inhibit generation of gas and/or coke increases the totalliquid product yield of the process.

In certain embodiments, the inorganic salt catalyst may include two ormore inorganic salts. A minimum DSC temperature for each of theinorganic salts may be determined. The minimum DSC temperature of theinorganic salt catalyst may be below the minimum DSC temperature of atleast one of the inorganic metal salts in the inorganic salt catalyst.For example, the inorganic salt catalyst may include potassium carbonateand cesium carbonate. Potassium carbonate and cesium carbonate exhibitDSC temperatures greater than 500° C. A K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalystexhibits a DSC temperature in a range from about 290-300° C.

In some embodiments, the TAP temperature may be between the DSCtemperature of at least one of the inorganic salts and the DSCtemperature of the inorganic salt catalyst. For example, the TAPtemperature of the inorganic salt catalyst may be in a range from about350-500° C. The DSC temperature of the same inorganic salt catalyst maybe in a range from about 200-300° C., and the DSC temperature of theindividual salts may be at least 500° C. or at most 1000° C.

An inorganic salt catalyst that has a TAP and/or DSC temperature betweenabout 150-500° C., about 200-450° C., or about 300-400° C., and does notundergo decomposition at these temperatures, in many embodiments, can beused to catalyze conversion of high molecular weight and/or highviscosity compositions (for example, crude feed) to liquid products.

In certain embodiments, the inorganic salt catalyst may exhibitincreased conductivity relative to individual inorganic salts duringheating of the inorganic salt catalyst in a temperature range from about200-600° C., about 300-500° C., or about 350-450° C. Increasedconductivity of the inorganic salt catalyst is generally attributed tothe particles in the inorganic salt catalyst becoming mobile. The ionicconductivity of some inorganic salt catalysts changes at a lowertemperature than the temperature at which ionic conductivity of a singlecomponent of the inorganic salt catalyst changes.

Ionic conductivity of inorganic salts may be determined by applyingOhm's law: V=IR, where V is voltage, I is current, and R is resistance.To measure ionic conductivity, the inorganic salt catalyst may be placedin a quartz vessel with two wires (for example, copper wires or platinumwires) separated from each other, but immersed in the inorganic saltcatalyst.

FIG. 7 is a schematic of a system that may be used to measure ionicconductivity. Quartz vessel 156 containing sample 158 may be placed in aheating apparatus and heated incrementally to a desired temperature.Voltage from source 160 is applied to wire 162 during heating. Theresulting current through wires 162 and 164 is measured at meter 166.Meter 166 may be, but is not limited to, a multimeter or a Wheatstonebridge. As sample 158 becomes less homogeneous (more mobile) withoutdecomposition occurring, the resistivity of the sample should decreaseand the observed current at meter 166 should increase.

In some embodiments, at a desired temperature, the inorganic saltcatalyst may have a different ionic conductivity after heating, cooling,and then heating. The difference in ionic conductivities may indicatethat the crystal structure of the inorganic salt catalyst has beenaltered from an original shape (first form) to a different shape (secondform) during heating. The ionic conductivities, after heating, areexpected to be similar or the same if the form of the inorganic saltcatalyst does not change during heating.

In certain embodiments, the inorganic salt catalyst has a particle sizein a range of about 10-1000 microns, about 20-500 microns, or about50-100 microns, as determined by passing the inorganic salt catalystthrough a mesh or a sieve.

The inorganic salt catalyst may soften when heated to temperatures above50° C. and below 500° C. As the inorganic salt catalyst softens, liquidsand catalyst particles may co-exist in the matrix of the inorganic saltcatalyst. The catalyst particles may, in some embodiments, self-deformunder gravity, or under a pressure of at least 0.007 MPa, or at most0.101 MPa, when heated to a temperature of at least 300° C., or at most800° C., such that the inorganic salt catalyst transforms from a firstform to a second form. Upon cooling of the inorganic salt catalyst toabout 20° C., the second form of the inorganic salt catalyst isincapable of returning to the first form of the inorganic salt catalyst.The temperature at which the inorganic salt transforms from the firstform to a second form is referred to as the “deformation” temperature.The deformation temperature may be a temperature range or a singletemperature. In certain embodiments, the particles of the inorganic saltcatalyst self-deform under gravity or pressure upon heating to adeformation temperature below the deformation temperature of any of theindividual inorganic metal salts. In some embodiments, an inorganic saltcatalyst includes two or more inorganic salts that have differentdeformation temperatures. The deformation temperature of the inorganicsalt catalyst differs, in some embodiments, from the deformationtemperatures of the individual inorganic metal salts.

In certain embodiments, the inorganic salt catalyst is liquid and/orsemiliquid at, or above, the TAP and/or DSC temperature. In someembodiments, the inorganic salt catalyst is a liquid or a semiliquid atthe minimum TAP and/or DSC temperature. At or above the minimum TAPand/or DSC temperature, liquid or semiliquid inorganic salt catalystmixed with the crude feed may, in some embodiments, form a separatephase from the crude feed. In some embodiments, the liquid or semiliquidinorganic salt catalyst has low solubility in the crude feed (forexample, from about 0 grams to about 0.5 grams, about 0.0000001-0.2grams, or about 0.0001-0.1 grams of inorganic salt catalyst per gram ofcrude feed) or is insoluble in the crude feed (for example, from about 0grams to about 0.05 grams, about 0.000001-0.01 grams, or about0.00001-0.001 grams of inorganic salt catalyst per gram of crude feed)at the minimum TAP temperature.

In some embodiments, powder x-ray diffraction methods are used todetermine the spacing of the atoms in the inorganic salt catalyst. Ashape of the D₀₀₁ peak in the x-ray spectrum may be monitored and therelative order of the inorganic salt particles may be estimated. Peaksin the x-ray diffraction represent different compounds of the inorganicsalt catalyst. In powder x-ray diffraction, the D₀₀₁ peak may bemonitored and the spacing between atoms may be estimated. In aninorganic salt catalyst that contains highly ordered inorganic saltatoms, a shape of the D₀₀₁ peak is relatively narrow. In an inorganicsalt catalyst (for example, a K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst) thatcontains randomly ordered inorganic salt atoms, the shape of the D₀₀₁peak may be relatively broad or the D₀₀₁ peak may be absent. Todetermine if the disorder of inorganic salt atoms changes duringheating, an x-ray diffraction spectrum of the inorganic salt catalystmay be taken before heating and compared with an x-ray diffractionspectrum taken after heating. The D₀₀₁ peak (corresponding to theinorganic salt atoms) in the x-ray diffraction spectrum taken attemperatures above 50° C. may be absent or broader than the D₀₀₁ peaksin the x-ray diffraction spectrum taken at temperatures below 50° C.Additionally, the x-ray diffraction pattern of the individual inorganicsalt may exhibit relatively narrow D₀₀₁ peaks at the same temperatures.

Contacting conditions may be controlled such that the total productcomposition (and thus, the crude product) may be varied for a givencrude feed in addition to limiting and/or inhibiting formation ofby-products. The total product composition includes, but is not limitedto, paraffins, olefins, aromatics, or mixtures thereof. These compoundsmake up the compositions of the crude product and the non-condensablehydrocarbon gases.

Controlling contacting conditions in combination with the catalystdescribed herein may produce a total product with lower than predictedcoke content. Comparison of the MCR content of various crudes may allowcrudes to be ranked based on their tendency to form coke. For example, acrude with a MCR content of about 0.1 grams of MCR per gram of crudewould be expected to form more coke than a crude with a MCR content ofabout 0.001 grams of MCR per gram of crude. Disadvantaged crudestypically have MCR contents of at least 0.05 grams of MCR per gram ofdisadvantaged crude.

In some embodiments, the residue content and/or coke content depositedon the catalyst during a reaction period may be at most 0.1 grams, atmost 0.05 grams, or at most 0.03 grams of residue and/or coke per gramof catalyst. In certain embodiments, the weight of residue and/or cokedeposited on the catalyst is in a range from about 0.0001-0.1 grams,0.001-0.05 grams, or about 0.01-0.03 grams. In some embodiments, usedcatalyst is substantially free of residue and/or coke. In certainembodiments, contacting conditions are controlled such that at most0.015 grams, at most 0.01 grams, at most 0.005 grams, or at most 0.003grams of coke is formed per gram of crude product. Contacting a crudefeed with the catalyst under controlled contacting conditions produces areduced quantity of coke and/or residue relative to a quantity of cokeand/or residue produced by heating the crude feed in the presence of arefining catalyst, or in the absence of a catalyst, using the samecontacting conditions.

The contacting conditions may be controlled, in some embodiments, suchthat, per gram of crude feed, at least 0.5 grams, at least 0.7 grams, atleast 0.8 grams, or at least 0.9 grams of the crude feed is converted tothe crude product. Typically, between about 0.5-0.99 grams, about0.6-0.9 grams, or about 0.7-0.8 grams of the crude product per gram ofcrude feed is produced during contacting. Conversion of the crude feedto a crude product with a minimal yield of residue and/or coke, if any,in the crude product allows the crude product to be converted tocommercial products with a minimal amount of pre-treatment at arefinery. In certain embodiments, per gram of crude feed, at most 0.2grams, at most 0.1 grams, at most 0.05 grams, at most 0.03 grams, or atmost 0.01 grams of the crude feed is converted to non-condensablehydrocarbons. In some embodiments, from about 0 to about 0.2 grams,about 0.0001-0.1 grams, about 0.001-0.05 grams, or about 0.01-0.03 gramsof non-condensable hydrocarbons per gram of crude feed is produced.

Controlling a contacting zone temperature, rate of crude feed flow, rateof total product flow, rate and/or amount of catalyst feed, orcombinations thereof, may be performed to maintain desired reactiontemperatures. In some embodiments, control of the temperature in thecontacting zone may be performed by changing a flow of a gaseoushydrogen source and/or inert gas through the contacting zone to dilutethe amount of hydrogen and/or remove excess heat from the contactingzone.

In some embodiments, the temperature in the contacting zone may becontrolled such that a temperature in the contacting zone is at, above,or below desired temperature “T₁”. In certain embodiments, thecontacting temperature is controlled such that the contacting zonetemperature is below the minimum TAP temperature and/or the minimum DSCtemperature. In certain embodiments, T₁ may be about 30° C. below, about20° C. below, or about 10° C. below the minimum TAP temperature and/orthe minimum DSC temperature. For example, in one embodiment, thecontacting temperature may be controlled to be about 370° C., about 380°C., or about 390° C. during the reaction period when the minimum TAPtemperature and/or minimum DSC temperature is about 400° C.

In other embodiments, the contacting temperature is controlled such thatthe temperature is at, or above, the catalyst TAP temperature and/or thecatalyst DSC temperature. For example, the contacting temperature may becontrolled to be about 450° C., about 500° C., or about 550° C. duringthe reaction period when the minimum TAP temperature and/or minimum DSCtemperature is about 450° C. Controlling the contacting temperaturebased on catalyst TAP temperatures and/or catalyst DSC temperatures mayyield improved crude product properties. Such control may, for example,decrease coke formation, decrease non-condensable gas formation, orcombinations thereof.

In certain embodiments, the inorganic salt catalyst may be conditionedprior to addition of the crude feed. In some embodiments, theconditioning may take place in the presence of the crude feed.Conditioning the inorganic salt catalyst may include heating theinorganic salt catalyst to a first temperature of at least 100° C., atleast 300° C., at least 400° C., or at least 500° C., and then coolingthe inorganic salt catalyst to a second temperature of at most 250° C.,at most 200° C., or at most 100° C. In certain embodiments, theinorganic salt catalyst is heated to a temperature in a range from about150-700° C., about 200-600° C., or about 300-500° C., and then cooled toa second temperature in a range from about 25-240° C., about 30-200° C.,or about 50-90° C. The conditioning temperatures may be determined bydetermining ionic conductivity measurements at different temperatures.In some embodiments, conditioning temperatures may be determined fromDSC temperatures obtained from heat/cool transitions obtained by heatingand cooling the inorganic salt catalyst multiple times in a DSC.Conditioning of the inorganic salt catalyst may allow contact of a crudefeed to be performed at lower reaction temperatures than temperaturesused with conventional hydrotreating catalysts.

In some embodiments, a content of naphtha, distillate, VGO, or mixturesthereof, in the total product, may be varied by changing a rate of totalproduct removal from a contacting zone. For example, decreasing a rateof total product removal tends to increase contacting time of the crudefeed with the catalyst. Alternately, increasing pressure relative to aninitial pressure may increase contacting time, may increase a yield of acrude product, may increase incorporation of hydrogen from the gasesinto a crude product for a given mass flow rate of crude feed orhydrogen source, or may alter combinations of these effects. Increasedcontacting times of the crude feed with the catalyst may produce anincreased amount of diesel, kerosene, or naphtha and a decreased amountof VGO relative to the amounts of diesel, kerosene, naphtha, and VGOproduced at shorter contacting times. Increasing the contacting time ofthe total product in the contacting zone may also change the averagecarbon number of the crude product. Increased contacting time may resultin a higher weight percentage of lower carbon numbers (and thus, ahigher API gravity).

In some embodiments, the contacting conditions may be changed over time.For example, the contacting pressure and/or the contacting temperaturemay be increased to increase the amount of hydrogen that the crude feeduptakes to produce the crude product. The ability to change the amountof hydrogen uptake of the crude feed, while improving other propertiesof the crude feed, increases the types of crude products that may beproduced from a single crude feed. The ability to produce multiple crudeproducts from a single crude feed may allow different transportationand/or treatment specifications to be satisfied.

Uptake of hydrogen may be assessed by comparing H/C of the crude feed toH/C of the crude product. An increase in the H/C of the crude productrelative to H/C of the crude feed indicates incorporation of hydrogeninto the crude product from the hydrogen source. Relatively low increasein H/C of the crude product (about 20%, as compared to the crude feed)indicates relatively low consumption of hydrogen gas during the process.Significant improvement of the crude product properties, relative tothose of the crude feed, obtained with minimal consumption of hydrogenis desirable.

The ratio of hydrogen source to crude feed may also be altered to alterthe properties of the crude product. For example, increasing the ratioof the hydrogen source to crude feed may result in crude product thathas an increased VGO content per gram of crude product.

In certain embodiments, contact of the crude feed with the inorganicsalt catalyst in the presence of light hydrocarbons and/or steam yieldsmore liquid hydrocarbons and less coke in a crude product than contactof a crude feed with an inorganic salt catalyst in the presence ofhydrogen and steam. In embodiments that include contact of the crudefeed with methane in the presence of the inorganic salt catalyst, atleast a portion of the components of the crude product may includeatomic carbon and hydrogen (from the methane) which has beenincorporated into the molecular structures of the components.

In certain embodiments, the volume of crude product produced from acrude feed contacted with the hydrogen source in the presence of theinorganic salt catalyst is at least 5% greater, at least 10% greater, orat least 15%, or at most 100% greater than a volume of crude productproduced from a thermal process at STP. The total volume of crudeproduct produced by contact of the crude feed with the inorganic saltcatalyst may be at least 110 vol % of the volume of the crude feed atSTP. The increase in volume is believed to be due to a decrease indensity. Lower density may generally be at least partially caused byhydrogenation of the crude feed.

In certain embodiments, a crude feed having, per gram of crude feed, atleast 0.02 grams, at least 0.05 grams, or at least 0.1 grams of sulfur,and/or at least 0.001 grams of Ni/V/Fe is contacted with a hydrogensource in the presence of an inorganic salt catalyst without diminishingthe activity of the catalyst.

In some embodiments, the inorganic salt catalyst can be regenerated, atleast partially, by removal of one or more components that contaminatethe catalyst. Contaminants include, but are not limited to, metals,sulfides, nitrogen, coke, or mixtures thereof. Sulfide contaminants maybe removed from the used inorganic salt catalyst by contacting steam andcarbon dioxide with the used catalyst to produce hydrogen sulfide.Nitrogen contaminants may be removed by contacting the used inorganicsalt catalyst with steam to produce ammonia. Coke contaminants may beremoved from the used inorganic salt catalyst by contacting the usedinorganic salt catalyst with steam and/or methane to produce hydrogenand carbon oxides. In some embodiments, one or more gases are generatedfrom a mixture of used inorganic salt catalyst and residual crude feed.

In certain embodiments, a mixture of used inorganic salt (for example,K₂CO₃/Rb₂CO₃/Cs₂CO₃; KOH/Al₂O₃; Cs₂CO₃/CaCO₃; or NaOH/KOH/LiOH/ZrO₂),unreacted crude feed and/or residue and/or coke may be heated to atemperature in a range from about 700-1000° C. or from about 800-900° C.until the production of gas and/or liquids is minimal in the presence ofsteam, hydrogen, carbon dioxide, and/or light hydrocarbons to produce aliquid phase and/or gas. The gas may include an increased quantity ofhydrogen and/or carbon dioxide relative to reactive gas. For example,the gas may include from about 0.1-99 moles or from about 0.2-8 moles ofhydrogen and/or carbon dioxide per mole of reactive gas. The gas maycontain a relatively low amount of light hydrocarbons and/or carbonmonoxide. For example, less than about 0.05 grams of light hydrocarbonsper gram of gas and less than about 0.01 grams of carbon monoxide pergram of gas. The liquid phase may contain water, for example, greaterthan 0.5-0.99 grams, or greater than 0.9-0.9 grams of water per gram ofliquid.

In some embodiments, the used catalyst and/or solids in the contactingzone may be treated to recover metals (for example, vanadium and/ornickel) from the used catalyst and/or solids. The used catalyst and/orsolids may be treated using generally known metal separation techniques,for example, heating, chemical treating, and/or gasification.

EXAMPLES

Non-limiting examples of catalyst preparations, testing of catalysts,and systems with controlled contacting conditions are set forth below.

Example 1 Preparation of a K—Fe Sulfide Catalyst

A K—Fe sulfide catalyst was prepared by combining 1000 grams of ironoxide (Fe₂O₃) and 580 g of potassium carbonate with 412 grams ofde-ionized water to form a wet paste. The wet paste was dried at 200° C.to form an iron oxide/potassium carbonate mixture. The ironoxide/potassium carbonate mixture was calcined at 500° C. to form aniron oxide/potassium carbonate mixture. The iron oxide/potassiumcarbonate mixture was reacted with hydrogen to form a reducedintermediate solid that included iron metal. Hydrogen addition wasperformed over 48 hours at 450° C. and 11.5-12.2 MPa (about 1665-1765psi). The intermediate solid was passed through a 40-mesh sieve withminimal force.

The intermediate solid was added incrementally at a rate to control theevolution of heat and produced gas to a VGO/m-xylene/elemental sulfurmixture at 100° C. After addition of the intermediate solid, theresulting mixture was incrementally heated to 300° C. and maintained at300° C. for about 1 hour. The solvent/catalyst mixture was cooled tobelow 100° C. and the sulfurized catalyst was separated from themixture. The sulfurized catalyst was isolated by filtration in a dry-boxunder an argon atmosphere, and washed with m-xylene to produce 544.7grams of the K—Fe sulfide catalyst. The K—Fe sulfide catalyst waspowdered by passing the catalyst through a 40-mesh sieve.

The resulting K—Fe sulfide catalyst was analyzed using x-ray diffractiontechniques. From analysis of the x-ray diffraction spectrum, it wasdetermined that the catalyst included troilite (FeS), K—Fe sulfide(KFeS₂), pyrrhotite, and iron oxides (for example, magnetite, Fe₃O₄). Apeak associated with iron disulfide (for example, pyrite, FeS₂) was notobserved in the x-ray diffraction spectrum.

Example 2 Contact of a Crude Feed with a Hydrogen Source in the Presenceof a K—Fe Sulfide Catalyst

A 600 mL continuously stirred tank reactor (composed of 316 stainlesssteel) was fitted with a bottom inlet feed port, a single vapor effluentport, three thermocouples located in the reactor interior, and ashaftdriven 1.25-inch diameter six-blade Rushton turbine.

The K—Fe sulfide catalyst (110.3 grams) prepared as described in Example1 was charged to the reactor. Hydrogen gas was metered at about 8,000Nm³/m³ (50,000 SCFB) into the reactor and mixed with bitumen(Lloydminster region of Canada). The bitumen entered the reactor throughthe bottom inlet feed port to form a hydrogen/crude feed mixture. Duringthe reaction run period of about 185 hours, hydrogen gas and crude feedwere continuously fed into the reactor and product was continuouslyremoved through the effluent vapor port of the reactor. Crude feed wasfed at a rate of 67.0 g/hr to maintain the crude feed liquid level atabout 60% of the reactor volume. A 50 milli-curie ¹³⁷Cs gamma ray sourceand a sodium iodide scintillation detector were used to measure theliquid level in the reactor.

The hydrogen gas/crude feed was contacted with the catalyst at anaverage internal reactor temperature of 430° C. Contacting of thehydrogen/crude feed with the catalyst produced a total product in theform of the reactor effluent vapor. The reactor effluent vapor exitedthe vessel through the single upper exit port. The reactor head waselectrically heated to 430° C. to prevent internal condensation of thereactor effluent vapor on the reactor head.

After exiting the reactor, the reactor effluent vapor was cooled andseparated in a high pressure gas/liquid separator and a low-pressuregas/liquid separator to produce a liquid stream and a gas stream. Thegas stream was sent to a countercurrent flow caustic scrubber to removeacidic gases, and thereafter quantified using standard chromatographictechniques. The total product included, per gram of total product, 0.918grams of crude product and 0.089 grams of non-condensable hydrocarbongases. About 0.027 grams of solids per gram of crude feed remained inthe reactor. Properties and compositions of the crude product and thenon-condensable hydrocarbon gases produced by this method are summarizedin Table 1 in FIG. 8, Table 2 in FIG. 9, and Table 3 in FIG. 10.

This example demonstrates a method of contacting a crude feed withhydrogen in the presence of the transition metal sulfide catalyst toproduce a total product with minimal concomitant generation of coke. Thetotal product included a crude product that was a liquid mixture at STPand has at most 0.1 grams of non-condensable hydrocarbon gases per gramof total product.

By comparing the results of the MCR content for the crude feed (13.7 wt%) in Table 1 to the solids formed during the process (2.7 wt %), it ispossible to see that the combination of the controlled conditions andthe catalyst produced a lower quantity of coke than that indicated bythe ASTM Method D4530.

The non-condensable hydrocarbons included C₂, C₃, and C₄ hydrocarbons.From the sum of the weight percentages of the C₂ hydrocarbons listed inTable 2 (20.5 grams), the ethylene content per gram of total C₂hydrocarbons may be calculated. The C₂ hydrocarbons of the hydrocarbongases included 0.073 grams of ethylene per gram of total C₂hydrocarbons. From the sum of the weight percentages of the C₃hydrocarbons listed in Table 2 (23.9 grams), the propene content pergram of total C₃ hydrocarbons may be calculated. The C₃ hydrocarbons ofthe non-condensable hydrocarbon gases included 0.21 grams of propene pergram of total C₃ hydrocarbons. The C₄ hydrocarbons of thenon-condensable hydrocarbon gases had an iso-butane to n-butane weightratio of 0.2.

This example demonstrates a method to produce a crude product thatincludes at least 0.001 grams of hydrocarbons with a boiling rangedistribution of at most 204° C. (400° F.) at 0.101 MPa, at least 0.001grams of hydrocarbons with a boiling range distribution between about204° C. and about 300° C. at 0.101 MPa, at least 0.001 grams ofhydrocarbons with a boiling range distribution between about 300° C. andabout 400° C. at 0.101 MPa, and at least 0.001 grams of hydrocarbonswith a boiling range distribution between about 400° C. and about 538°C. (1,000° F.) at 0.101 MPa. The hydrocarbons that had a boiling rangedistribution below 204° C. included iso-paraffins and n-paraffins, andthe ratio of such iso-paraffins to the n-paraffins was at most 1.4.

The crude product included boiling point distributions that areassociated with naphtha, kerosene, diesel, and VGO. The crude producthad at least 0.001 grams of naphtha and the naphtha portion of the crudeproduct had an octane number of at least 70. The naphtha portion of thecrude product had a benzene content of at most 0.01 grams of benzene pergram of naphtha. The naphtha portion of the crude product had at most0.15 grams of olefins per gram of naphtha. The naphtha portion of thecrude product had at least 0.1 grams of monocyclic ring aromatics pergram of naphtha.

The crude product had at least 0.001 grams of kerosene. The keroseneportion of the crude product had a freezing point below −30° C. Thekerosene portion of the crude product included aromatics, and thekerosene portion of the crude product had an aromatics content of atleast 0.3 grams of aromatics per gram of kerosene. The kerosene portionof the crude product had at least 0.2 grams of monocyclic ring aromaticsper gram of kerosene.

The crude product had at least 0.001 grams of diesel. The dieselfraction of the crude product included aromatics, and the dieselfraction of the crude product had an aromatics content of at least 0.4grams of aromatics per gram of diesel.

The crude product had at least 0.001 grams of VGO. The VGO portion ofthe crude product included aromatics, and the VGO had an aromaticscontent of at least 0.5 grams of aromatics per gram of VGO.

Example 3 Preparation of a K—Fe Sulfide Catalyst in the Absence ofHydrocarbon Diluent

A K—Fe sulfide catalyst was prepared by combining 1000 g of iron oxideand 173 g of potassium carbonate with 423 g of de-ionized water to forma wet paste. The wet paste was processed as described in Example 1 toform the intermediate solid. The intermediate solid was passed through a40-mesh sieve with minimal force.

In contrast to Example 2, the intermediate solid was mixed withelemental sulfur in the absence of a hydrocarbon diluent. In a dry-boxusing an argon atmosphere, the intermediate solid was mixed withpowdered elemental sulfur, placed in a sealed carbon steel cylinder,heated to 400° C., and maintained at 400° C. for about 1 hour. Thesulfurized catalyst was recovered from the carbon steel reactor as asolid. The potassium-iron sulfide catalyst was crushed to a powder usinga mortar and pestle such that the resulting catalyst powder passedthrough a 40-mesh sieve.

The resulting potassium iron sulfide catalyst was analyzed using x-raydiffraction techniques. From analysis of the x-ray diffraction spectrum,it was determined that the catalyst included pyrite (FeS₂), iron sulfide(FeS), and pyrrhotite (Fe_(1-x)S). Mixed potassium-iron sulfide or ironoxide species were not detected using x-ray diffraction techniques.

Example 4 Contact of a Crude Feed With a Hydrogen Source in the Presenceof a K—Fe Sulfide Catalyst at an Increased Ratio of Gaseous Hydrogen toCrude Feed

The apparatus, crude feed, and reaction procedure were the same as inExample 2, except that the ratio of hydrogen gas to crude feed was about16,000 Nm³/m³ (100,000 SCFB). The K—Fe sulfide catalyst (75.0 grams),prepared as described in Example 3, was charged to the reactor.

Properties of the crude product produced from this method are summarizedin Table 1 in FIG. 8 and in Table 3 in FIG. 10. The weight percentage ofVGO produced in Example 4 is greater than the weight percentage of VGOproduced in Example 2. The weight percentage of distillate produced inExample 4 is less than the weight percentage of distillate produced inExample 2. The API gravity of the crude product produced in Example 4 islower than the API gravity of the crude product produced in Example 2. Ahigher API gravity indicates hydrocarbons with a higher carbon numberwere produced.

After contact with the crude feed, the TMS catalyst in the reactor wasanalyzed. From this analysis, the transition metal sulfide catalyst,after being in the presence of the crude feed and hydrogen, includedK₃Fe₁₀S₁₄.

Example 5 TAP Testing of a K₂CO₃/Rb₂CO₃/Cs₂CO₃ Catalyst and theIndividual Inorganic Salts

In all TAP testing, a 300 mg sample was heated in a reactor of a TAPsystem from room temperature (about 27° C.) to 500° C. at a rate ofabout 50° C. per minute. Emitted water vapor and carbon dioxide gas weremonitored using a mass spectrometer of the TAP system.

The K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst supported on alumina showed a currentinflection of greater than 0.2 volts for emitted carbon dioxide and acurrent inflection of 0.01 volts for emitted water from the inorganicsalt catalyst at about 360° C. The minimum TAP temperature was about360° C., as determined by plotting the log 10 of the ion current versustemperature. FIG. 11 is a graphical representation of log 10 plots ofion current of emitted gases from the K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst(“log(I)”) versus temperature (“T”). Curves 168 and 170 are log 10values for the ion currents for emitted water and CO₂ from the inorganicsalt catalyst. Sharp inflections for emitted water and CO₂ from theinorganic salt catalyst occurs at about 360° C.

In contrast to the K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst, potassium carbonate andcesium carbonate had non-detectable current inflections at 360° C. forboth emitted water and carbon dioxide.

The substantial increase in emitted gas for the K₂CO₃/Rb₂CO₃/Cs₂CO₃catalyst demonstrates that inorganic salt catalysts composed of two ormore different inorganic salts may be more disordered than theindividual pure carbonate salts.

Example 6 DSC Testing of an Inorganic Salt Catalyst and IndividualInorganic Salts

In all DSC testing, a 10 mg sample was heated to 520° C. at a rate of10° C. per min, cooled from 520° C. to 0.0° C. at rate of 10° C. perminute, and then heated from 0° C. to 600° C. at a rate of 10.0° C. permin using a differential scanning calorimeter (DSC) Model DSC-7,manufactured by Perkin-Elmer (Norwalk, Conn., U.S.A.).

DSC analysis of a K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst during second heating ofthe sample shows that the salt mixture exhibited a broad heat transitionbetween 219° C. and 260° C. The midpoint of the temperature range wasabout 250° C. The area under heat transition curve was calculated to be−1.75 Joules per gram. The beginning of crystal disorder was determinedto start at the minimum DSC temperature of 219° C.

In contrast to these results, no definite heat transitions were observedfor cesium carbonate.

DSC analysis of a mixture of Li₂CO₃, Na₂CO₃, and K₂CO₃ during the secondheating cycle shows that the Li₂CO₃/Na₂CO₃/K₂CO₃ mixture exhibited asharp heat transition between 390° C. to 400° C. The midpoint of thetemperature range was about 385° C. The area under heat transition curvewas calculated to be −182 Joules per gram. The beginning of mobility isdetermined to start at the minimum DSC temperature of 390° C. The sharpheat transition indicates a substantially homogeneous mixture of salts.

Example 7 Ionic Conductivity Testing of an Inorganic Salt Catalysts oran Individual Inorganic Salt Relative to K₂CO₃

All testing was conducted by placing 3.81 cm (1.5 inches) of theinorganic salt catalysts or the individual inorganic salts in a quartzvessel with platinum or copper wires separated from each other, butimmersed in the sample in a muffle furnace. The wires were connected toa 9.55 volt dry cell and a 220,000 ohm current limiting resistor. Themuffle furnace was heated to 600° C. and the current was measured usinga microammeter.

FIG. 12 is a graphical representation of log plots of the sampleresistance relative to potassium carbonate resistance (“log(rK₂CO₃)”)versus temperature (“T”). Curves 172, 174, 176, 178, and 180 are logplots of K₂CO₃ resistance, CaO resistance, K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalystresistance, Li₂CO₃/K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst resistance, andNa₂CO₃/K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst resistance, respectively.

CaO (curve 174) exhibits relatively large stable resistance relative toK₂CO₃ (curve 172) at temperatures in a range between 380-500° C. Astable resistance indicates an ordered structure and/or ions that tendnot to move apart from one another during heating. TheK₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst, Li₂CO₃/K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst, andNa₂CO₃/K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst (see curves 176, 178, and 180) showa sharp decrease in resistivity relative to K₂CO₃ at temperatures in arange from 350-500° C. A decrease in resistivity generally indicatesthat current flow was detected during application of voltage to thewires embedded in the inorganic salt catalyst. The data from FIG. 12demonstrate that the inorganic salt catalysts are generally more mobilethan the pure inorganic salts at temperatures in a range from 350-600°C.

FIG. 13 is a graphical representation of log plots ofNa₂CO₃/K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst resistance relative to K₂CO₃resistance (“log(rK₂CO₃)”) versus temperature (“T”). Curve 182 is a plotof a ratio of Na₂CO₃/K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst resistance relative toK₂CO₃ resistance (curve 172) versus temperature during heating of theNa₂CO₃/K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst. After heating, theNa₂CO₃/K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst was cooled to room temperature andthen heated in the conductivity apparatus. Curve 184 is a log plot ofNa₂CO₃/K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst resistance relative to K₂CO₃resistance versus temperature during heating of the inorganic saltcatalyst after being cooled from 600° C. to 25° C. The ionicconductivity of the reheated Na₂CO₃/K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalystincreased relative to the ionic conductivity of the originalNa₂CO₃/K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst.

From the difference in ionic conductivities of the inorganic saltcatalyst during the first heating and second heating, it may be inferredthat the inorganic salt catalyst forms a different form (a second form)upon cooling that is not the same as the form (a first form) before anyheating.

Example 8 Flow Property Testing of an Inorganic Salt Catalyst

A 1-2 cm thick layer of powdered K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst was placedin a quartz dish. The dish was placed in a furnace and heated to 500° C.for about 1 hour. To determine flow properties of the catalyst, the dishwas manually tilted in the oven after heating. The K₂CO₃/Rb₂CO₃/Cs₂CO₃catalyst did not flow. When pressed with a spatula, the catalyst had aconsistency of taffy.

In contrast, the individual carbonate salts were free flowing powdersunder the same conditions.

A Na₂CO₃/K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst became liquid and readily flowed(similar, for example, to water) in the dish under the same conditions.

Examples 9-10 Contact of a Crude Feed with a Hydrogen Source in thePresence of a K₂CO₃/Rb₂CO₃/Cs₂CO₃ Catalyst and Steam

The following equipment and general procedure was used in Examples 9-27except where variations are described.

Reactor: A 250 mL Hastelloy C Parr Autoclave (Parr Model #4576) rated at35 MPa working pressure (5000 psi) at 500° C., was fitted with amechanical stirrer and an 800 watt Gaumer band heater on a Eurothermcontroller capable of maintaining the autoclave at ±5° C. from ambientto 625° C., a gas inlet port, a steam inlet port, one outlet port, and athermocouple to register internal temperature. Prior to heating, the topof the autoclave was insulated with glass cloth.Addition Vessel: An addition vessel (a 250 mL, 316 stainless steel hokevessel) was equipped with a controlled heating system, suitable gascontrol valving, a pressure relief device, thermocouples, a pressuregauge, and a high temperature control valve (Swagelok Valve # SS-4UW)capable of regulating flow of a hot, viscous, and/or pressurized crudefeed at a flow rate from 0-500 g/min. An outlet side of the hightemperature control valve was attached to the first inlet port of thereactor after crude feed was charged to the addition vessel. Prior touse, the addition vessel line was insulated.Product Collection Vapor from the reactor exited the outlet port of thereactor and was introduced into a series of cold traps of decreasingtemperatures (dip tubes connected to a series of 150 mL, 316 stainlesssteel hoke vessels). Liquid from the vapor was condensed in the coldtraps to form a gas stream and a liquid condensate stream. Flow rate ofthe vapor from the reactor and through the cold traps was regulated, asneeded, using a back pressure regulator. A rate of flow and a total gasvolume for the gas stream exiting the cold traps were measured using awet test meter (Ritter Model # TG 05 Wet Test Meter). After exiting thewet test meter, the gas stream was collected in a gas bag (a Tedlar gascollection bag) for analysis. The gas was analyzed using GC/MS(Hewlett-Packard Model 5890, now Agilent Model 5890; manufactured byAgilent Technologies, Zion Ill., U.S.A.). The liquid condensate streamwas removed from the cold traps and weighed. Crude product and waterwere separated from the liquid condensate stream. The crude product wasweighed and analyzed.Procedure: Cerro Negro (137.5 grams) was charged to the addition vessel.The crude feed had an API gravity of 6.7. The crude feed had, per gramof crude feed, a sulfur content of 0.042 grams, a nitrogen content of0.011 grams, and a total Ni/V content of 0.009 grams. The crude feed washeated to 150° C. The K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst (31.39 grams) wascharged to the reactor.

The K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst was prepared by combining of 16.44grams of K₂CO₃, 19.44 grams of Rb₂CO₃, and 24.49 grams of Cs₂CO₃. TheK₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst had a minimum TAP temperature of 360° C.The K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst had a DSC temperature of 250° C. Theindividual salts (K₂CO₃, Rb₂CO₃, and Cs₂CO₃) did not exhibit DSCtemperatures in a range from 50-500° C. This TAP temperature is abovethe DSC temperature of the inorganic salt catalyst and below the DSCtemperature of the individual metal carbonates.

The catalyst was heated rapidly to 450° C. under an atmospheric pressureflow of methane of 250 cm³/min. After reaching the desired reactiontemperature, steam at a rate of 0.4 mL/min, and methane at rate of 250cm³/min, was metered to the reactor. The steam and methane werecontinuously metered during the addition of the crude feed to thereactor over about 2.6 hours. The crude feed was pressurized into thereactor using 1.5 MPa (229 psi) of CH₄ over 16 minutes. Residual crudefeed (0.56 grams) remained in the addition vessel after the addition ofthe crude feed was complete. A decrease in temperature to 370° C. wasobserved during the addition of the crude feed.

The catalyst/crude feed mixture was heated to a reaction temperature of450° C. and maintained at that temperature for about 2 hours. After twohours, the reactor was cooled and the resulting residue/catalyst mixturewas weighed to determine a percentage of coke produced and/or notconsumed in the reaction.

From a difference in initial catalyst weight and coke/catalyst mixtureweight, 0.046 grams of coke remained in the reactor per gram of crudefeed. The total product included 0.87 grams of a crude product with anaverage API gravity of 13 and gas. The gas included unreacted CH₄,hydrogen, C₂ and C₄-C₆ hydrocarbons, and CO₂ (0.08 grams of CO₂ per gramof gas).

The crude product had, per gram of crude product, 0.01 grams of sulfurand 0.000005 grams of a total Ni and V. The crude product was notfurther analyzed.

In Example 10, the reaction procedures, conditions, crude feed, andcatalyst were the same as in Example 9. The crude product of Example 10was analyzed to determine boiling range distributions for the crudeproduct. The crude product had, per gram of crude product, 0.14 grams ofnaphtha, 0.19 grams of distillate, 0.45 grams of VGO, and residuecontent of 0.001 grams, and non-detectable amounts of coke.

Examples 9 and 10 demonstrate that contact of the crude feed with ahydrogen source in the presence of at most 3 grams of catalyst per 100grams of crude feed produces a total product that includes a crudeproduct that is a liquid mixture at STP. The crude product had a residuecontent of at most 30% of the residue content of the crude feed. Thecrude product had a sulfur content and total Ni/V content of at most 90%of the sulfur content and Ni/V content of the crude feed.

The crude product included at least 0.001 grams of hydrocarbons with aboiling range distribution of at most 200° C. at 0.101 MPa, at least0.001 grams of hydrocarbons with a boiling range distribution between200-300° C. at 0.101 MPa, at least 0.001 grams of hydrocarbons with aboiling range distribution between 400-538° C. (1000° F.) at 0.101 MPa.

Examples 11-12 Contact of a Crude Feed with a Hydrogen Source in thePresence of the K₂CO₃/Rb₂CO₃/Cs₂CO₃ Catalyst and Steam

The reaction procedures, conditions, and the K₂CO₃/Rb₂CO₃/Cs₂CO₃catalyst in Examples 11 and 12 were the same as in Example 9, exceptthat 130 grams of crude feed (Cerro Negro) and 60 grams of theK₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst were used. In Example 11, methane was usedas the hydrogen source. In Example 12, hydrogen gas was used as thehydrogen source. A graphical representation of the amounts ofnon-condensable gas, crude product, and coke is depicted in FIG. 14.Bars 186 and 188 represent wt % coke produced, bars 190 and 192represent wt % liquid hydrocarbons produced, and bars 194 and 196represent wt % gas produced, based on the weight of the crude feed.

In Example 11, 93 wt % of crude product (bar 192), 3 wt % of gas (bar196), and 4 wt % of coke (bar 188), based on the weight of the CerroNegro, was produced.

In Example 12, 84 wt % of crude product (bar 190), 7 wt % of gas (bar194), and 9 wt % of coke were produced (bar 186), based on the weight ofthe Cerro Negro.

Examples 11 and 12 provide a comparison of the use of methane as ahydrogen source to the use of hydrogen gas as a hydrogen source. Methaneis generally less expensive to produce and/or transport than hydrogen,thus a process that utilizes methane is desirable. As demonstrated,methane is at least as effective as hydrogen gas as a hydrogen sourcewhen contacting a crude feed in the presence of an inorganic saltcatalyst to produce a total product.

Examples 13-14 Producing a Crude Product with a Selected API Gravity

The apparatus, reaction procedure and the inorganic salt catalyst werethe same as in Example 9, except that the reactor pressure was varied.

Example 13, the reactor pressure was 0.1 MPa (14.7 psi) during thecontacting period. A crude product with API gravity of 25 at 15.5° C.was produced. The total product had hydrocarbons with a distribution ofcarbon numbers in a range from 5 to 32 (see curve 198 in FIG. 15).

In Example 14, the reactor pressure was 3.4 MPa (514.7 psi) during thecontacting period. A crude product with API gravity of 51.6 at 15.5° C.was produced. The total product had hydrocarbons with a distribution ofcarbon numbers in a range from 5 to 15 (see curve 200 in FIG. 15).

These examples demonstrate methods for contacting the crude feed withhydrogen in the presence of an inorganic salt catalyst at variouspressures to produce a crude product with a selected API gravity. Byvarying the pressure, a crude product with a higher or lower API gravitywas produced.

Examples 15-16 Contact of a Crude Feed in the Presence of aK₂CO₃/Rb₂CO₃/Cs₂CO₃ Catalyst or Silicon Carbide in the Absence of anExternal Hydrogen Source

In Examples 15 and 16, the apparatus, crude feed, and reaction procedurewere the same as in Example 9, except that the crude feed and catalyst(or silicon carbide) were directly charged into the reactor at the sametime. Carbon dioxide (CO₂) was used as a carrier gas. In Example 15, 138grams of Cerro Negro was combined with 60.4 grams of theK₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst (same catalyst as in Example 9). In Example16, 132 g of Cerro Negro was combined with 83.13 grams of siliconcarbide (40 mesh, Stanford Materials; Aliso Viejo, Calif.). Such siliconcarbide is believed to have low, if any, catalytic properties under theprocess conditions described herein.

In each example, the mixture was heated to a reaction temperature of500° C. over a period of about 2 hours. The CO₂ was metered into thereactor at a rate of 100 cm³/min. Vapor generated from the reactor wascollected in the cold traps and a gas bag using a back pressure of about3.2 MPa (479.7 psi). Crude product from the cold traps was consolidatedand analyzed.

In Example 15, 36.82 grams (26.68 wt %, based on the weight of the crudefeed) of a colorless hydrocarbon liquid with API gravity of at least 50was produced from contact of the crude feed with the inorganic saltcatalyst in the carbon dioxide atmosphere.

In Example 16, 15.78 grams (11.95 wt %, based on the weight of the crudefeed) of a yellow hydrocarbon liquid with an API gravity of 12 wasproduced from contact of the crude feed with silicon carbide in thecarbon dioxide atmosphere.

Although the yield in Example 15 is low, the in-situ generation of ahydrogen source in the presence of the inorganic salt catalyst isgreater than the in-situ generation of hydrogen under non-catalyticconditions. The yield of crude product in Example 16 is one-half of theyield of crude product in Example 15. Example 15 also demonstrates thathydrogen is generated during contact of the crude feed in the presenceof the inorganic salt and in the absence of a gaseous hydrogen source.

Examples 17-20 Contact of a Crude Feed with a Hydrogen Source in thePresence of K₂CO₃/Rb₂CO₃/Cs₂CO₃ Catalyst, Calcium Oxide, and SiliconCarbide at Atmospheric Conditions

The apparatus, reaction procedure, crude feed and the inorganic saltcatalyst were the same as in Example 9, except that the Cerro Negro wasadded directly to the reactor instead of addition through the additionvessel and hydrogen gas was used as the hydrogen source. The reactorpressure was 0.101 MPa (14.7 psi) during the contacting period. Thehydrogen gas flow rate was 250 cm³/min. Reaction temperatures, steamflow rates, and percentages of crude product, gas, and coke produced aretabulated in Table 4 in FIG. 16.

In Examples 17 and 18, the K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst was used. InExample 17, the contacting temperature was 375° C. In Example 18, thecontacting temperature was in a temperature range from 500-600° C.

As shown in Table 4 (FIG. 16), for Examples 17 and 18, when thetemperature was increased from 375° C. to 500° C., production of gasincreased from 0.02 grams to 0.05 grams of gas per gram of totalproduct. Coke production, however, decreased from 0.17 grams to 0.09grams of coke per gram of crude feed at the higher temperature. Thesulfur content of the crude product also decreased from 0.01 grams to0.008 grams of sulfur per gram of crude product at the highertemperature. Both crude products had H/C of 1.8.

In Example 19, a crude feed was contacted with CaCO₃ under conditionssimilar to the conditions described for Example 18. Percentages of crudeproduct, gas, and coke production are tabulated in Table 4 in FIG. 16.Gas production increased in Example 19 relative to the gas production inExample 18. Desulfurization of the crude feed was not as effective as inExample 18. The crude product produced in Example 19 had, per gram ofcrude product, 0.01 grams of sulfur as compared to the sulfur content of0.008 grams per gram of crude product for the crude product produced inExample 18.

Example 20 is a comparative example for Example 18. In Example 20, 83.13grams of silicon carbide instead of the inorganic salt catalyst wascharged to the reactor. Gas production and coke production significantlyincreased in Example 20 relative to the gas production and cokeproduction in Example 18. Under these non-catalytic conditions, 0.22grams of coke per gram of crude product, 0.25 grams of non-condensablegas, and 0.5 grams of crude product were produced. The crude productproduced in Example 20 had 0.036 grams of sulfur per gram of crudeproduct, compared to of 0.01 grams of sulfur per gram of crude productproduced in Example 18.

These examples demonstrated that the catalysts used in Examples 17 and18 provide improved results over non-catalytic conditions andconventional metal salts. At 500° C., and a hydrogen flow rate of 250cm³/min, the amounts of coke and non-condensable gas were significantlylower than the amounts of coke and of non-condensable gas produced undernon-catalytic conditions.

In examples using inorganic salt catalysts (See Examples 17-18 in Table4, FIG. 16), a decrease was observed in the weight percent of producedgas relative to the produced gas formed during the control experiment(for example, Example 20 in Table 4, FIG. 16). From the quantity ofhydrocarbons in the produced gas, the thermal cracking of the crude feedis estimated to be at most 20 wt %, at most 15 wt %, at most 10 wt %, atmost 5 wt %, or none, based on the total amount of crude feed contactedwith a hydrogen source.

Examples 21 and 22 Contact of a Crude Feed with a Gaseous HydrogenSource in the Presence of Water and a K₂CO₃/Rb₂CO₃/Cs₂CO₃ Catalyst orSilicon Carbide

Apparatus in Examples 21 and 22 were the same as in Example 9 exceptthat hydrogen gas was used as the hydrogen source. In Example 21, 130.4grams of Cerro Negro was combined with 30.88 grams of theK₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst to form a crude feed mixture. In Example22, 139.6 grams of Cerro Negro was combined with 80.14 grams of siliconcarbide to form the crude feed mixture.

The crude feed mixture was charged directly into the reactor. Thehydrogen gas was metered at 250 cm³/min into the reactor during theheating and holding periods. The crude feed mixture was heated to 300°C. over about 1.5 hours and maintained at 300° C. for about 1 hour. Thereaction temperature was increased to 400° C. over about 1 hour andmaintained at 400° C. for about 1 hour. After the reaction temperaturereached 400° C., water was introduced into the reactor at a rate of 0.4g/min in combination with the hydrogen gas. Water and hydrogen weremetered into the reactor for the remaining heating and holding periods.After maintaining the reaction mixture at 400° C., the reactiontemperature was increased to 500° C. and maintained at 500° C. for about2 hours. Generated vapor from the reactor was collected in the coldtraps and a gas bag. Liquid product from the cold traps was consolidatedand analyzed.

In Example 21, 86.17 grams (66.1 wt %, based on the weight of the crudefeed) of a dark reddish brown hydrocarbon liquid (crude product) andwater (97.5 g) were produced as a vapor from contact of the crude feedwith the K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst in the hydrogen atmosphere.

In Example 22, water vapor and a small amount of gas was produced fromthe reactor. The reactor was inspected, and a dark brown viscoushydrocarbon liquid was removed from the reactor. Less than 50 wt % ofthe dark brown viscous liquid was produced from contact of the crudefeed with silicon carbide in the hydrogen atmosphere. A 25% increase inyield of crude product was observed in Example 21 relative to a yield ofcrude product produced in Example 22.

Example 21 demonstrates an improvement of the properties of the crudeproduct produced using methods described herein relative to a crudeproduct produced using hot water. Specifically, the crude product inExample 21 was lower boiling than the crude product from Example 22, asdemonstrated by the crude product produced in Example 22 not being ableto be produced as a vapor. The crude product produced in Example 21 hadenhanced flow properties relative to the crude product produced inExample 22, as determined by visual inspection.

Examples 23-24 Contact of a Crude Feed with a Hydrogen Source in thePresence of a K₂CO₃/Rb₂CO₃/Cs₂CO₃ Catalyst to Produce a Crude Productwith Increased Volume Relative to a Crude Product Volume Produced underNon-Catalytic Conditions

The apparatus, crude feed, inorganic catalyst, and reaction procedurewas the same as described in Example 9, except the crude feed wasdirectly charged to the reactor and hydrogen gas was used as thehydrogen source. The crude feed (Cerro Negro) had an API gravity 6.7 anda density of 1.02 g/mL at 15.5° C.

In Example 23, 102 grams of the crude feed (about 100 mL of crude feed)and 31 grams of K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst were charged to thereactor. A crude product (87.6 grams) with an API gravity of 50 and adensity of 0.7796 g/mL at 15.5° C. (112 mL) was produced.

In Example 24, 102 grams of crude feed (about 100 mL of crude feed) and80 grams of silicon carbide were charged to the reactor. A crude product(70 grams) of with an API gravity of 12 and a density of 0.9861 g/mL at15.5° C. (about 70 mL) was produced.

Under these conditions, the volume of the crude product produced fromExample 23 was approximately 10% greater than the volume of the crudefeed. The volume of the crude product produced in Example 24 wassignificantly less (40% less) than the volume of crude product producedin Example 23. A significant increase in volume of product enhances aproducer's ability to generate more volume of crude product per volumeof input crude.

Example 25 Contact of a Crude Feed with a Hydrogen Source in thePresence of a K₂CO₃/Rb₂CO₃/Cs₂CO₃ Catalyst, Sulfur, and Coke

The apparatus and reaction procedure were the same as in Example 9,except that the steam was metered into the reactor at 300 cm³/min. TheK₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst was prepared by combining 27.2 grams ofK₂CO₃, 32.2 grams of Rb₂CO₃ and 40.6 grams of Cs₂CO₃.

The crude feed (130.35 grams) and K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst (31.6grams) was charged to the reactor. The Cerro Negro crude included, pergram of crude feed, 0.04 grams total aromatics content in a boilingrange distribution between 149-260° C. (300-500° F.), 0.000640 grams ofnickel and vanadium combined, 0.042 grams of sulfur, and 0.56 grams ofresidue. API gravity of the crude feed was 6.7.

Contact of the crude feed with methane in the presence of theK₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst produced, per gram of crude feed, 0.95grams of total product, and 0.041 grams of coke.

The total product included, per gram of total product, 0.91 grams ofcrude product and 0.028 grams of hydrocarbon gas. The total gascollected included, per mole of gas, 0.16 moles of hydrogen, 0.045 molesof carbon dioxide, and 0.025 moles of C₂ and C₄-C₆ hydrocarbons, asdetermined by GC/MS. The balance of the gas was methane, air, carbonmonoxide, and a trace (0.004 moles) of evaporated crude product.

The crude product was analyzed using a combination of gas chromatographyand mass spectrometry. The crude product included a mixture ofhydrocarbons with a boiling range between 100-538° C. The total liquidproduct mixture included 0.006 grams ethyl benzene (a monocyclic ringcompound with a boiling point of 136.2° C. at 0.101 MPa) per gram ofmixture. This product was not detected in the crude feed.

The used catalyst (“first used catalyst”) was removed from the reactor,weighed, and then analyzed. The first used catalyst had an increase inweight from 31.6 grams to a total weight of 37.38 grams (an increase of18 wt %, based on the weight of the original K₂CO₃/Rb₂CO₃/Cs₂CO₃catalyst). The first used catalyst included 0.15 grams of additionalcoke, 0.0035 grams of sulfur, 0.0014 grams of Ni/V, and 0.845 grams ofK₂CO₃/Rb₂CO₃/Cs₂CO₃ per gram of used catalyst.

Additional crude feed (152.71 grams) was contacted with the first usedcatalyst (36.63 grams) to produce 150 grams of recovered total productafter losses. The total product included, per gram of total product,0.92 grams of liquid crude product, 0.058 grams of additional coke, and0.017 grams of gas. The gas included, per mole of gas, 0.18 moles ofhydrogen, 0.07 grams of carbon dioxide, and 0.035 moles of C₂-C₆hydrocarbons. The balance of the gas was methane, nitrogen, some air,and traces of evaporated oil product (<1% mole).

The crude product included a mixture of hydrocarbons with a boilingrange between 100-538° C. The portion of the mixture with a boilingrange distribution below 149° C. included, per mole of total liquidhydrocarbons, 0.018 mole % of ethyl benzene, 0.04 mole % of toluene,0.03 mole % of meta-xylene, and 0.060 mole % of para-xylene (monocyclicring compounds with a boiling points below 149° C. at 0.101 MPa). Theseproducts were not detectable in the crude feed.

The used catalyst (“second used catalyst”) was removed from the reactor,weighed, and then analyzed. The second used catalyst had an increase inweight from 36.63 grams to a total weight of 45.44 grams (an increase of43 wt %, based on the weight of the original K₂CO₃/Rb₂CO₃/Cs₂CO₃catalyst). The second used catalyst included 0.32 grams of coke, and0.01 grams of sulfur, and 0.67 grams per gram of second used catalyst.

Additional crude feed (104 grams) was contacted with the second usedcatalyst (44.84 grams) to produce, per gram of crude feed, 104 grams oftotal product and 0.114 grams of coke was collected. A portion of thecoke was attributed to coke formation in the addition vessel due tooverheating the addition vessel since 104.1 grams of the 133 grams ofcrude feed transferred was crude feed.

The total product included, per gram of total product, 0.86 grams ofcrude product and 0.025 grams of hydrocarbon gas. The total gasincluded, per mole of gas, 0.18 moles of hydrogen, 0.052 moles of carbondioxide, and 0.03 moles of C₂-C₆ hydrocarbons. The balance of the gaswas methane, air, carbon monoxide, hydrogen sulfide, and a small traceof evaporated oil.

The crude product included a mixture of hydrocarbons with a boilingrange between 100-538° C. The portion of the mixture with a boilingrange distribution below 149° C. included, per gram of hydrocarbonmixture, 0.021 grams ethyl benzene, 0.027 grams of toluene, 0.042 gramsof meta-xylene, and 0.020 grams of para-xylene, determined as before byGC/MS.

The used catalyst (“third used catalyst”) was removed from the reactor,weighed, and then analyzed. The third used catalyst had an increase inweight from 44.84 grams to a total weight of 56.59 grams (an increase of79 wt %, based on the weight of the original K₂CO₃/Rb₂CO₃/Cs₂CO₃catalyst). Detailed elemental analysis of the third used catalyst wasperformed. The third used catalyst included, per gram of additionalmatter, 0.90 grams of carbon, 0.028 grams of hydrogen, 0.0025 grams ofoxygen, 0.046 grams of sulfur, 0.017 grams of nitrogen, 0.0018 grams ofvanadium, 0.0007 grams of nickel, 0.0015 grams of iron, and 0.00025grams of chloride with the balance being other transition metals such aschromium, titanium and zirconium.

As demonstrated in this example, coke, sulfur, and/or metals depositedon and/or in the inorganic salt catalyst do not affect the overall yieldof crude product (at least 80% for each run) produced by contact of acrude feed with a hydrogen source in the presence of the inorganic saltcatalyst. The crude product had a monocyclic aromatics content at least100 times the monocyclic ring aromatics content of the crude feed in aboiling range distribution below 149° C.

For the three runs, the average crude product yield (based on the weightof the crude feed) was 89.7 wt %, with a standard deviation of 2.6%; theaverage coke yield was 7.5 wt % (based on the weight of the crude feed),with a standard deviation of 2.7%, and the average weight yield ofgaseous cracked hydrocarbons was 2.3 wt % (based on the weight of thecrude feed) with a standard deviation of 0.46%. The comparatively largestandard deviation of both liquid and coke was due to the third trial,in which the temperature controller of the feed vessel failed,overheating the crude feed in the addition vessel. Even so, there is noapparent significant deleterious effect of even the large amounts ofcoke tested here on the activity of the catalyst system.

The ratio of C₂ olefins to total C₂ was 0.19. The ratio of C₃ olefin tototal C₃ was 0.4. The alpha olefins to internal olefins ratio of the C₄hydrocarbons was 0.61. The C₄ cis/trans olefins ratio was 6.34. Thisratio was substantially higher than the predicted thermodynamic C₄cis/trans olefins ratio of 0.68. The alpha olefins to internal olefinsratio of the C₅ hydrocarbons was 0.92. This ratio was greater than thepredicted thermodynamic C₅ alpha olefins to C₅ internal olefins ratio of0.194. The C₅ cis/trans olefins ratio was 1.25. This ratio was greaterthan the predicted thermodynamic C₅ cis/trans olefins ratio of 0.9.

Example 26 Contact of a Relatively High Sulfur Containing Crude Feedwith a Hydrogen Source in the Presence of the K₂CO₃/Rb₂CO₃/Cs₂CO₃Catalyst

The apparatus and reaction procedure were the same as described inExample 9, except that the crude feed, methane, and steam werecontinuously fed to the reactor. The level of feed in the reactor wasmonitored using a change in weight of the reactor. Methane gas wascontinuously metered at 500 cm³/min to the reactor. Steam wascontinuously metered at 6 g/min to the reactor.

The inorganic salt catalyst was prepared by combining 27.2 grams ofK₂CO₃, 32.2 grams of Rb₂CO₃ and 40.6 grams of Cs₂CO₃. TheK₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst (59.88 grams) was charged to the reactor.

A crude feed (bitumen, Lloydminster, Canada) having an API gravity of9.4, a sulfur content of 0.02 grams of sulfur, and a residue content of0.40 grams, per gram of crude feed, was heated in the addition vessel to150° C. The hot bitumen was continuously metered from the additionvessel at 10.5 g/min to the reactor in an attempt to maintain the crudefeed liquid level of 50% of the reactor volume, however, the rate wasinsufficient to maintain that level.

The methane/steam/crude feed was contacted with the catalyst at anaverage internal reactor temperature of 456° C. Contacting of themethane/steam/crude feed with the catalyst produced a total product (inthis example in the form of the reactor effluent vapor).

A total of 1640 grams of crude feed was processed over 6 hours. From adifference in initial catalyst weight and residue/catalyst mixtureweight, 0.085 grams of coke per gram of crude feed remained in thereactor. From contact of the crude feed with the methane in the presenceof the K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst, 0.93 grams of total product pergram of crude feed was produced. The total product included, per gram oftotal product, 0.03 grams of gas and 0.97 grams of crude product,excluding the amount of methane and water used in the reaction.

The gas included, per gram of gas, 0.014 grams of hydrogen, 0.018 gramsof carbon monoxide, 0.08 grams of carbon dioxide, 0.13 grams of hydrogensulfide, and 0.68 grams of non-condensable hydrocarbons. From the amountof hydrogen sulfide generated, it may be estimated that the sulfurcontent of the crude feed was reduced by 18 wt %. As shown in thisexample, hydrogen, carbon monoxide, and carbon dioxide were produced.The molar ratio of carbon monoxide to carbon dioxide was 0.4.

The C₂-C₅ hydrocarbons included, per gram of hydrocarbons, 0.30 grams ofC₂ compounds, 0.32 grams of C₃ compounds, 0.26 grams of C₄ compounds,and 0.10 grams of C₅ compounds. The weight ratio of iso-pentane ton-pentane in the non-condensable hydrocarbons was 0.3. The weight ratioof isobutane to n-butane in the non-condensable hydrocarbons was 0.189.The C₄ compounds had, per gram of C₄ compounds, a butadiene content of0.003 grams. A weight ratio of alpha C₄ olefins to internal C₄ olefinswas 0.75. A weight ratio of alpha C₅ olefins to internal C₅ olefins was1.08.

The data in Example 25 demonstrates that continuous processing of arelatively high sulfur crude feed with the same catalyst in the presenceof coke did not diminish the activity of the inorganic salt catalyst,and produced a crude product suitable for transportation.

Example 27 Contact of a Crude Feed with a Hydrogen Source in thePresence of a K₂CO₃/Rb₂CO₃/Cs₂CO₃ Catalyst and Coke

The apparatus and reaction procedure was performed using conditions asdescribed in Example 26. The K₂CO₃/Rb₂CO₃/Cs₂CO₃ catalyst (56.5 grams)was charged to the reactor. A total of 2550 grams of crude feed wasprocessed over 6 hours. From a difference in initial catalyst weight andresidue/catalyst mixture weight, 0.114 grams of coke per gram of crudefeed remained in the reactor, based on the weight of the crude feed. Atotal of 0.89 grams of total product per gram of crude feed wasproduced. The total product included, per gram of total product, 0.04grams of gas and 0.96 grams of crude product, excluding the amount ofmethane and water used in the reaction.

The gas included, per gram of gas, 0.021 grams of hydrogen, 0.018 gramsof carbon monoxide, 0.052 grams of carbon dioxide, 0.18 grams ofhydrogen sulfide, and 0.65 grams of non-condensable hydrocarbons. Fromthe amount of hydrogen sulfide produced, it may be estimated that thesulfur content of the crude feed was reduced by 14 wt %, based on theweight of the crude feed. As shown in this example, hydrogen, carbonmonoxide, and carbon dioxide were produced. The molar ratio of carbonmonoxide to carbon dioxide was 0.6.

The C₂-C₆ hydrocarbons included, per gram of C₂-C₆ hydrocarbons, 0.44grams of C₂ compounds, 0.31 grams of C₃ compounds, 0.19 grams of C₄compound and 0.068 grams of C₅ compounds. The weight ratio ofiso-pentane to n-pentane in the non-condensable hydrocarbons was 0.25.The weight ratio of iso-butane to n-butane in the non-condensablehydrocarbons was 0.15. The C₄ compounds had, per gram of C₄ compounds, abutadiene content of 0.003 grams.

This example demonstrates that repeated processing of the a relativelyhigh sulfur crude feed (2550 grams of crude feed) with the same catalyst(56.5 grams) in the presence of coke did not diminish the activity ofthe inorganic salt catalyst, and produced a crude product suitable fortransportation.
